Nuevas excavaciones en Cueva del Medio. Procesos de formación de la cueva y avances en los estudios de interacción entre cazadores-recolectores y fauna extinta (Pleistoceno Final, Patagonia Meridional)

New studies at Cueva del Medio, Ultima Esperanza, Chile, are presented. Some of the main cave formation and sediment accumulation processes were identified. New excavations indicated that extinct fauna was using the cave at least since 14,000 radiocarbon years BP. Human occupations at the end of the Pleistocene were confirmed with new findings and radiocarbon dates. The importance of extinct fauna in the human subsistence was less important than previously sustained
